These guys used to come around my area and the older kids would setup traps to rob 'em for both speakers and cash. Mid evening in fall/spring when it still gets dark out early. Most of these cats ride with two people so they don't get jumped/robbed by other crews but you can't compare them to gangsters, at all. Just annoying fuckers trying to get by with shady flips, half way crooks..
When they approach you, just say "i used to run your hustle, you hit 5 sales yet today?" < they'll leave you alone every time, and if they DID hit 5 sales, and actually told you, then chances are they have a few K on their person, prime targets for karma. OP: Next time don't call the cops, tell a few of your local G's/thugs/etc. if you know any, they'll thrive on this shit.
